HESI Fundamentals Practice Test
1. Mr. Landon is scheduled to undergo a tracheostomy. Which nursing action is essential during tracheal suctioning?
- A. Using a water-soluble lubricant.
- B. Administering 100% oxygen before and after suctioning.
- C. Ensuring that the suction catheter is open during insertion.
- D. Assisting the client to assume a semi-Fowler's position during suctioning.
Correct answer: B
Rationale: Administering 100% oxygen before and after suctioning is crucial to prevent hypoxia, which can occur during tracheal suctioning. Hypoxia can lead to serious complications, making the provision of oxygen essential in maintaining adequate oxygenation levels for the patient undergoing tracheal suctioning. Choice A is incorrect because using a water-soluble lubricant is not directly related to the essential nursing action during tracheal suctioning. Choice C is incorrect as ensuring that the suction catheter is open during insertion is a basic requirement and not the essential action for oxygenation. Choice D is incorrect because assisting the client to assume a semi-Fowler's position is beneficial for comfort and airway alignment but is not as crucial as administering oxygen to prevent hypoxia.
2. What are the primary pathophysiological mechanisms responsible for ascites in liver failure?
- A. Decreased liver enzymes.
- B. Increased hydrostatic pressure in portal circulation.
- C. High bilirubin levels.
- D. Fluid shifts due to decreased serum proteins.
Correct answer: B
Rationale: The correct answer is B: Increased hydrostatic pressure in portal circulation. Ascites in liver failure is primarily caused by fluid shifts from the intravascular space to the interstitial space due to increased hydrostatic pressure in the portal circulation. Choice A is incorrect as ascites is not caused by decreased liver enzymes. Choice C is incorrect as high bilirubin levels are not the primary mechanism for ascites in liver failure. Choice D is incorrect as fluid shifts in ascites are due to decreased serum proteins, not increased serum proteins.
3. The client has a chest tube. What is the most important action for the nurse to take?
- A. Ensure the chest tube remains unclamped at all times.
- B. Empty the chest tube every 2 hours.
- C. Keep the drainage system below the level of the chest.
- D. Assess for subcutaneous emphysema.
Correct answer: C
Rationale: Keeping the drainage system below the level of the chest (C) is crucial to ensure proper drainage and prevent backflow of air or fluid into the chest cavity. This position helps maintain the integrity of the closed drainage system. Ensuring the chest tube remains unclamped at all times (A) allows for continuous drainage. Emptying the chest tube (B) should be done as needed, not routinely every 2 hours. Assessing for subcutaneous emphysema (D) is important but not the most critical action in this scenario.
4. A male client presents to the clinic stating that he has a high-stress job and is having difficulty falling asleep at night. The client reports having a constant headache and is seeking medication to help him sleep. Which intervention should the nurse implement?
- A. Determine the client’s sleep and activity pattern
- B. Obtain a prescription for the client to take when stressed
- C. Refer the client for a sleep study and neurological follow-up
- D. Teach coping strategies to use when feeling stressed
Correct answer: D
Rationale: Teaching coping strategies is an appropriate first intervention for a client experiencing sleep difficulties and stress. It can help manage stress and improve sleep without immediately resorting to medication. By teaching coping strategies, the nurse empowers the client to address the underlying issues contributing to his sleep problems rather than just providing a temporary solution. Referring for a sleep study and neurological follow-up may be considered later if the client's sleep issues persist despite implementing coping strategies. Determining the client’s sleep and activity pattern may be helpful but addressing coping strategies is more beneficial in managing stress-related sleep issues. Obtaining a prescription for the client to take when stressed does not address the root cause of the sleep problem and may lead to dependency on medication rather than promoting long-term solutions.
5. A client with psoriasis is prescribed topical corticosteroids. What side effect should the nurse monitor for?
- A. Monitor for weight gain and skin thinning.
- B. Assess for increased sensitivity to sunlight.
- C. Monitor for hair loss and excessive bruising.
- D. Report any signs of increased redness or itching.
Correct answer: D
Rationale: The correct answer is D. When a client with psoriasis is prescribed topical corticosteroids, the nurse should monitor for signs of increased redness or itching. This is because topical corticosteroids can cause skin thinning and increased redness if overused. Choices A, B, and C are incorrect because weight gain, sensitivity to sunlight, hair loss, and excessive bruising are not typically associated with the use of topical corticosteroids.
